It’s possible that GLib will eventually be compiled against a version of
libc which supports `close_range()` (hence `HAVE_CLOSE_RANGE` will be
defined), but then run against an older kernel which doesn’t support it.
In this case, we want to fall back to `fdwalk()`, which should work on
such systems.

The function declaration we use changed a bit since then.
In particular, some arguments became const. See following commit.
libselinux-2.2 was released on 20131030, and is widely available in
all major stable distributions.

"we found that the const security_context_t declarations in libselinux
are incorrect; const char * was intended, but const security_context_t
translates to char * const and triggers warnings on passing const char *
from the caller. Easiest fix is to replace them all with const char *."

They extend the behavior of, respectively, -p and -s options of the
glib test framework
Currently test suite are only run for one level under -p path, for
example, testfilemonitor -p /monitor would execute the following tests:
/monitor/atomic-replace
/monitor/file-changes
/monitor/dir-monitor
/monitor/dir-not-existent
/monitor/cross-dir-moves
With the --run-prefix the sub-test suite file will be executed:
/monitor/atomic-replace
/monitor/file-changes
/monitor/dir-monitor
/monitor/dir-not-existent
/monitor/cross-dir-moves
/monitor/file/hard-links
The --skip-prefix and run-prefix seems symmetrical, but there is a
difference with skip towards run:
--skip-prefix will use a prefix while --run-prefix only work for a valid test path.
For example and for the following test family:
/monitor/atomic-replace
/monitor/file-changes
/monitor/dir-monitor
/monitor/dir-not-existent
/monitor/cross-dir-moves
/monitor/file/hard-links
while --run-prefix /mon will not execute anything, --skip-prefix /mon
will skip all of these tests.

- Add a test for parsing FILE scheme from uri
It had taken from GST test_protocol_case
- Add a split uri test with encoded spaces in its path
It had taken from GST test_uri_get_location
- Add tests for g_uri_is_valid
It had taken from GST test_uri_misc
Note that the 4 followings uri failed under gst_uri_is_valid but not
under g_uri_is_valid
B:\\foo.txt

- Add tests for g_uri_split
It had taken from GST test_url_parsing
- Add tests for test_uri_normalize and test_uri_parsing_relative
The test URI had been taken from GST test_url_normalization
- Add tests for test_uri_iter_params
It had taken from GST test_url_unescape_equals_in_http_query

It still works, and deprecating it would be quite disruptive (as it’s
used in headers), so amend the documentation to point people to
`G_NORETURN` instead.

The problem occurs because we keep a pointer inside the allocated block,
instead of a pointer to the start of the block. This memory exists for
the lifetime of the application, so let's silence it.
This is probably abuse of VALGRIND_MALLOCLIKE_BLOCK(), which is really
intended for use in memory allocators, but gtype.c already uses it in
two other places, and it's a practical solution. I wrote another larger
fix for this issue that involves keeping an array of extra pointers when
running under valgrind. This is simpler.

Note we cannot use VALGRIND_FREELIKE_BLOCK() in freelist_free() because we
have not actually freed the FreeListNode and need to dereference it in
freelist_alloc() to decide whether to reuse the block. That would result
in a use-after-free warning before we would get a chance to call
VALGRIND_MALLOCLIKE_BLOCK() in the reuse path.
Also note that this free list only ever grows: it never shrinks for the
lifetime of the application, so nothing here will ever be truely freed,
although unused elements are eligible for reuse.

For URIs produced in string form, the path should be normalized and port
omitted when the default one is used. When querying the path and port of
a GUri (using getters or g_uri_split()) the normalized path and the
default port should be returned when they were omitted in the parsed URI.

Use `g_time_zone_new_identifier()` instead so you can get error
